Short answer: The right Green River rafting trip depends on your time and appetite for whitewater. A 1-day Flaming Gorge trip suits families and first-timers with Class II water. A 3-day Flaming Gorge or Gates of Lodore trip adds camping. A 4-day Gates of Lodore trip is the full Class III-IV canyon experience through Dinosaur National Monument, including the Yampa confluence at Echo Park.

Which Green River Rafting Trip Should I Book?
Dinosaur River Expeditions runs Green River rafting trips on two distinct sections: the Flaming Gorge tailwater near Vernal, Utah, and the Gates of Lodore canyon through Dinosaur National Monument. Which one to book comes down to how much time you have and how big a rapid you’re after.
Think of it as a ladder. Start at a 1-day Flaming Gorge float if you want a taste of the river with minimal commitment. Step up to a 3-day trip, on either section, if you want a full camping experience. Go all the way to the 4-day Gates of Lodore expedition if you want the biggest whitewater and canyon scenery the Green River offers.

1-Day Flaming Gorge: Best for Families and First-Timers
This is a 7-mile float below Flaming Gorge Dam, starting near Vernal, Utah. Rapids like Mother-in-Law and Bridge Rapid run Class II, mild enough for kids as young as 5 but still splashy enough to be fun. It’s the trip to book if you’re short on time or testing the whitewater waters for the first time. Adult pricing is $109, youth is $89, and senior/military is $99, not including guide gratuity or the online booking fee.
3-Day Flaming Gorge: Camping Without the Big Rapids
Same Class II water as the day trip, stretched into a 3-day camping trip with riverside beach camps and guide-cooked meals. It’s a good pick for families who want the multi-day camping experience without Class III-IV whitewater. Adult pricing runs $1,039.
3-Day and 4-Day Gates of Lodore: The Real Whitewater
This is a different section of the same river, launching from the Gates of Lodore in Colorado’s Browns Park and running through Dinosaur National Monument. The rapids here, Disaster Falls, Triplet Falls, and Hell’s Half Mile, run genuine Class III-IV, all named by the John Wesley Powell expedition in 1869. The 4-day version continues to Split Mountain and floats past Echo Park, where the Yampa River joins the Green beneath Steamboat Rock, a landmark no other Green River trip in the region includes.
Do Green River Rafting Trips Require a Permit?
Not with a guided trip. Private boaters entering Dinosaur National Monument (the Gates of Lodore section) apply through an NPS lottery at Recreation.gov, applications accepted December 1 through January 31. Guided trips with Dinosaur River Expeditions travel under our NPS concession permit, so there’s no lottery to win. The Flaming Gorge section outside the monument has separate, simpler access rules that our trips already cover.
When Do Green River Trips Run?
Both sections of the Green River are fed by dam releases (Flaming Gorge Dam for both stretches), which means a longer, more predictable season than free-flowing rivers. Trips run late May through early September, with Gates of Lodore departures continuing into early September some years.
